In plain language
The bundle of nerves running through the spine that carries signals between the brain and body.

Where you'll see this
This wording turns up on Cervical Spine MRI reports — MRI imaging of the spine. A cervical (neck) MRI shows the seven neck vertebrae, the discs between them, the spinal cord as it passes through, and the nerves that travel to the shoulders and arms. Doctors order it for neck pain, arm numbness or tingling, weakness, or after an injury. As with the low back, many findings it describes are common age-related changes seen in people without symptoms, so the report is read together with how you feel.
Questions worth asking your doctor
- Do the MRI findings match where I feel neck or arm symptoms?
- Are these changes typical for my age, or does anything stand out?
- What non-surgical approaches, like physical therapy, might help?
- Are there symptoms that would mean I should be seen more urgently?
- Do I need any follow-up imaging, and when?
How common is this?
The spinal cord is described on every neck and upper back MRI. It is the bundle of nerve tissue running from the brain down through the spinal canal, carrying signals to and from the body. It ends around the first or second lumbar vertebra, which is why lower back reports describe nerve roots and a sac rather than cord.
When should I worry?
The cord is the structure whose involvement changes the seriousness of a spine report. Most degenerative findings — discs, facet joints, foraminal narrowing — affect nerve roots and are managed conservatively. Compression or signal change within the cord itself is a different category, because cord tissue tolerates pressure poorly and recovers slowly. Symptoms that point that way — clumsiness in the hands, difficulty walking, changes affecting both sides, problems with bladder control — carry more weight than the images and warrant prompt assessment.
What happens next
Where the cord is normal, its mention is routine anatomy. Where the report describes contact or mild flattening without symptoms, that is common in the neck and usually watched. Where there is genuine compression with symptoms, or signal change within the cord, the pathway is specialist and generally more urgent, because the aim is to prevent damage rather than reverse it.
Frequently asked questions
- Where does the spinal cord end?
- Around the first or second lumbar vertebra in an adult. Below that the canal contains the cauda equina, a loose bundle of nerve roots, which is why lumbar reports describe roots and a sac rather than cord.
- What does cord signal change mean?
- That the cord tissue itself looks altered on MRI, usually brighter on T2 images. It is a more significant finding than compression alone and is assessed alongside the neurological examination.
- Is cord compression an emergency?
- It depends on the degree and how fast it developed. New or rapidly worsening symptoms — weakness, walking difficulty, bladder changes — need urgent assessment. Longstanding mild contact without symptoms is a common finding managed differently.
